|
Pushes outward into capsular space
|
|
|
Pushes inward on the visceral capillary membrane
|
|
|
Pulls solutes into the capillary
|
|
|
Creates “positive pressure”
|
Detailed explanation-1: -The force of hydrostatic pressure means that as blood moves along the capillary, fluid moves out through its pores and into the interstitial space. This movement means that the pressure exerted by the blood will become lower, as the blood moves along the capillary, from the arterial to the venous end.
Detailed explanation-2: -This is the capsular hydrostatic pressure. These fluids exert pressures in opposing directions. Net fluid movement will be in the direction of the lower pressure.
Detailed explanation-3: -When fluid enters the capillaries, it is initially pushed out because the hydrostatic pressure pressing outward is greater than the osmotic pressure pushing inward. Although osmotic pressure stays constant throughout the capillary length, hydrostatic pressure decreases towards the venule end of the capillary.
